Study of adsorption and degradation of acid orange 7 on the surface of CeO2 u…

Abstract. Cerium dioxide was prepared by the precipitation method and found to be an efficient photocatalyst to degrade azodyes under visible light irradiation. Nonbiodegradable azodyes acid orange 7 (AO7) was selected asmodal target to examine the photocatalytic activity of CeO2. AO7 could be efficiently degraded in aqueous suspension of CeO2 under visible light illumination. The catalyst …
